Sadler recently passed away in a car accident at the age of 24. He was a beloved member of the Spartan community, and this will give the school another opportunity to honor him.
Usually there is a 10-year waiting period before a player can be inducted into the school's Hall of Fame, but the waiting period was waived for Sadler.
In a press release, Michigan State Athletic Director Mark Hollis praised Sadler and explained the decision.
"Mike Sadler embodied everything great about being a Spartan. His excellence on the football field and in the classroom was surpassed only by the first-class manner in which he represented not only Spartan football, but Michigan State University. After careful consideration and a thorough examination of his credentials, we decided to waive the waiting period and induct him immediately."
As a four-year starter with Michigan State, Sadler was an All-American and helped the Spartans win a Rose Bowl. Off the field, he was known for his kind heart and witty sense of humor.
Sadler will be inducted into the Hall of Fame along with the rest of the 2016 class on Thursday, September 22.
